Description:
HS-40 is an erythroid-specific DNAse I hypersensitive site and is the major regulatory element of the human α-globin locus, located 40 kb upstream of the ζ-globin gene of the human alpha globin gene cluster. The human alpha globin gene cluster located on chromosome 16 spans about 30 kb and includes seven alpha like globin genes and pseudogenes: 5'- HBZ - HBZP1 - HBM - HBAP1 - HBA2 - HBA1 - HBQ1 -3'. Analysis of HS-40 has shown that it contains multiple binding sites for the erythroid-restricted transcription factors GATA1 and NF-E2. Removal of HS-40 site from a mouse model which recapitulates human α globin expression severely reduces α globin expression.

Synonyms: MCS-R2
